To all w iz/m, it may concern:

' Be it known that 1, PAUL FLEMMING Cox, of Battle Creek, in the countyof Calhoun and State of Michigan, have invented certain new and usefulImprovements in Printingiresses; and I hereby declare that the followring is a full, clear, and exact description tl'iereof, reference beinghad to the accompanying (iYi-LWJHgS, which form part of thisspecification.

This invention is an improvement in web printing presses in whicherfected impresone are produced upon t e web from fiat forms. of type bymoving impression-cylind s and its princi al object is to shorten thetravel of the cylin ers approximately half or ess. 1 In other words,where stationary beds are used andtwo sets of forms are arranged on eachbed the cylinder will have to travel but the length or Width of one forminstead core, and this is accomplished by providing two cylinders tooperate upon each bed and separating the forms. on such beds into spononly one part or half of the forms on such bed, the cylinders operating,preferably, simultaneously upon the formsone cylinder nd. its half-formprinting parts of the web rnt The two cylindiirs and" their forms,lowever, make their impressionsupon the ch in close juxtaposition, sothat theefl'ect the same as if both forms were printed by ne cylindertraveling over both forms. By ins shortening the travel of the cylindersre speed of the press is proportionately in- .ased.

Further jobjects oi" the invention are to ake the press very low down,so that the .ds and allparts will be within easy reach of e o orator andthe forms can be readily mace on or removed from the beds.

The presentinvention also enables such a crass to produce papers oflarge size from a ogil. ab and dispenses with the necessity sing formersat the i' older, the web can '3 slitted longitudinally into page lengths1 .(l assembled before reaching the folder or 1 "a ittii ig-cylinders.

The invention is illustrated in the accomanying drawings, which show onepractical Torin of web-perfecting printing-pross emidying the inventionand is summarized in .laims following the description of such .he lengthor width of both forms here-' no parts and having each cylinder operatepped by the other cvlinder and its half In said drawings, Figure 1. is aside elevation of the complete press. Fig. 2 is a longitudinal sectionthrough such press. Figs. 3, 4, 5, and 6 are diagrammatical views illus'trating the method of printing the web. Fig. 7 is a detail view showingthe arrangement of forms on the bed. Fig. 8 is a detail section on line8 8, Fig. i. Fig. 9 is a detail plan view illustrating the meth od ofsplitting and assembling the webs.

In the drawings, A B represent two horizontal typebeds, arrangedpreferably in the same plane and securely bolted in the ordinary mannerto the main frames of the press.

Above the bed A and adapted to cooperate with. the forms thereon areimpressioncylinders a and a, which are respectively adapted to cooperatewith the forms 1 and 2 lying upon the bed A. Similarly above bed B, arejournaled impression-0ylindcrs b 1),

adapted to respectively cooperate with forms 3, as shown.

The several impressioncylinders are pref during their.non-printingstrokes, and, as shown, the cylinders in each pair are journaled ineccentric-boxes C, which are provided with arms (7, connected by a rodor bar C extending alongside of the press, and each box also has an arm0, carrying a roller adapted to engage cams c on the main frames, asimlicatcd, those parts being so constructed that the cylinders ill bethrown o lf impression during their one stroke or travel of thecylinders and will be thrown on impression during the forward orprinting stroke of the same. The cams may be disccmnectiblo oradjustable, so that the cylinders can be thrown off impression and theweb-feeding devices put out of. action, and then the cylinders run toink up the forms without any printing taking lace.

As indicator-l in Fig. 1, t 1e cylinder-carriers 3 3 are operated bypitman-rods. J,

pivotally connected at one end to studs on the cylinrlcr-carriers and atthe other end to i crank-pins J on mam crank-gears J which intermesh,and one of these gears J meshes with a small driving-gear J on the shaft1", to which power is applied in any known manner. Each bed A and B isadapted to carry forms for four or more pages. These forms arepreferably placed on each bed in two rows, as shown at 1 and 2 on bed Aand at 1' 2 on bed B. The cylinder (1 operates on the forms in row 1 andthe cylinder a operates on the forms in row 2 at each outward orprinting stroke of the cylinders a a. Thus two impressions aresimultaneously made on the web. On the return stroke of cylinders a, ano impressions are made, as the impression is thrown ofi. The cylindersover each bed are spaced sufiiciently far apart to enable the inkingmechanism to be inserted therebetween'. The forms on each bed arepreferably inked from a common fountain and inking system arrangedbetween and traveling with the impressioncylinders. Thus the forms onbed A may be supplied with ink from a fountain E by means of theductor-roller e, drum 6, distributing-rollers e e ,-and form-rollers ec, all mounted on carriers 3. The form-rollers 0 lie near the cylindersa a, respectively, and each respectively supplies ink to one of theforms on bed A. The left-hand form-roller e supplies ink to theleft-hand form 1 and the righthand roller 6 supplies ink to therighthand form 2. A similar inking mechanism is mounted on carriers 3'between cylinders b b to supply ink to the forms 1 2 on bed B.

In order to prevent the form-rollers reversing while upon the forms, thecylinders and form-rollers c are sufficiently far apart to'all'ow therollers to clear their related forms the point-of reverse, as indicatedin Fig. 2 of the drawings, where the form-rollers are shown as clear ofboth forms 2 and 1*, and at the completion of the innermost strokes ofthe pitmen the form-rollers would be in the same position between theforms 1 and 2 that the forms 2 and 1 are shown as occupying. The formson each bed are also separated.

sufficiently to .enable the forms to clear the inking-rollers and thecylinders at the time of reverse. I

In order to shorten the stroke of the cylinder-carriers, the type-formsare preferably arranged transversely of the beds in two rows, asindicated in Fig. 7. .[f printing a twelve-page paper, each row of forms1 2 and l 2 -would contain three pages of matter arranged transverselyof the press, and preferably, for reasons hereinafter explained, insteadof arranging these forms with the columns running longitudinally of thepress we arrange them with the columns running transversely of thepress, so that instead of the column-forms being side by side they areend to end, as indicated in Fig. 7, and this enables us to materiallyshorten the travel of the reciprocating impression-cylinders, as theforms are of course narrower than they are long. This arrangement offorms enables the web after being perfected to be slit longitiulinallyand the papers assembled at the folder with a simple qm'irterturn of thesplit web, as indicated in Fig. 9. In this way the webs can be slit andthe pages assembled at the folder without necessarily passing them overany former, which arrangement greatly simplifies the construction of thepress and facilitates the assembling of the web.

The web is supplied from a roll W, which maybe conveniently supported atone end of the press, as shown in the drawings. The web is led in underan idler 5. then between the continuously running feedingin mcchan ism,comprising a roll G, mounted upon and around the shaft J of one set ofgears J, and

a series of tapes G, coacting with roll G in the usual manner, the tapesbeing guided over idlers and provided with suitable tensioning devices.The roll G is of such diame ter that it will-feed the desired length ofweb say thirty-five inches-for each reciprocation of thecylimler-carriage. The web then passes over a guide-roller g", thenaround a fixed guide-roller then is looped around a looping-roller 6 andpassed around a fixed guide 16",.and thence passes to and over a guide 9and down under cylinder (1., then over guide 9 and above the inkingmechanism to a guide-roller 9 down under cylinder (1/, up over guide g,then under and over a guiding andcoaxing roller g. The guides g g g gare mounted on the carriers 3 and travel with cylinders a a, and guidesb h 71 h are mounted on carriers 3. The guides 16 r) may be rotated byany suitable means (not shown) to coax the web forward. Guide g is shownas mounted in the upper ends of pivoted levers 7, which can be adjustedto move the roller '9 in or out. From guide 9 the web passes back to andover a guide it" on carrier 3*, then down under cylinder 1), then upover guide if, back above the second inking mechanism to a guide It,down under cylinder 1),

up over a guide It, thence around a second rolls.

The rollers g or g may be mounted in adjustable supports on the carriersto'msure proper registration or sequence between the impressionsproduced on the web from the lever 6 pivoted at 6 on the frame and havbyroll .l. 'lhewebmay be slit longitiulin'ally forms 1 2 by cylinders a a,and the rollers h or it may be mounted in adjustable supports for a likepurpose.

l The looping-rollers 6* 6 ma be, as shown, mounted on opposite ends 0reciprocatory bars 6, which are operated by means of a ing rollers ontheir lower ends engaging racecams 6 on the shaft of one of thecrank-gears J thecam and levers being so 'proportioned as to move therollers in one direction during impressions and in the oppositedirection between impressions, so that the roller 6" takes up the webfed in by the feed mechanism during impressions, while roller 6 gives upa like amount of web to the delivery mechanism. After impressions thereverse movements of the looping-rollers shifts part of the web throughthe pressroller 6" taking up in its loop the web given out of its loopby rollers 6", the coaction of the looping-rollers with the deliverymechanism after impressions suiiicing to shift the desired length ofweb. through the press after impressions. Any-other desired means forfeedin and shifting the web-may be employei I After the web has beenperfected it is divided longitudinally by slitters L, which. may beconveniently located adjacent to the roller t the web being slittedlongitudinally,- as indicated in Fig. 9, and then the slitted portionsof the web may be ledto and over angle-bars L located above the secondprinting mechanism and given a quarter-turn thereby and then assembledand led toa folder, (not shown,) which may be located at the side of thepress. By this arrangement of angle-bars'difi erei'it sized papers canbe printed on one web a'nd'the pages slit and assembled before passingto the cuttingcylinders and folded without the'employment of formers.

Operation: The operation may be summarized as follows: The web is led incontinually by the inleed-cylinder G- and alter being loo iedaronndroller 6" is passed be tween cy inders a u"and bed A, then is ledover suital'ile guidesto and between cylinders I) b and bed B, and thenled over suitable guides to and looped around a second looping-roller6", and is continually delivered and theslit portions given aquarter-turn over the tltil(i-2LFS and assembled before reaching thefolder. At each printing-stroke oi' the sets. of cylinders twoimpressions are produced on the web by the eoaction ol' cylindersd a.with the forms 1 and 2 on bed A and a similar number of impressions areprinted on the opposite side of the web in register with the firstimpressions by ylinders I; htcoacting with forms I 2 on bed B.

' curing two cylinders with each bed I am able to and bed, as aboveexplained, the web being 1 ed as hereinafter described. The firstcylin-' .der ((0 or 1)) in each pair, however, skips every otherpage-width of Web; but these skipped portions are printed by the secondcylinder in each pair, which skips the previouslyglprinted portions, theski ping oc-.

uring the return stroke 0' the cylinders and while the impression isthrown ofi". The press, as shownin Fig. 1, has just cornpleted aprinting-stroke and the impressioncylinders have ust been thrown off ofimpression and will at once commence their return nonprinting stroke totheir inner or central position, the sets of cylinders are preferablyarranged to move oppositely. While the cylinder-carriages are returning"ofi' impression, the looping-roller 6 will travel to the left, its loopbeing exhausted by the action of the other looping-roller 6*, whichtravels in unison therewith, (both rollers being moved simultaneously inthe same direction by bars 6,) and the required amount of web will betransferred or spaced forward to bring the desired spaces of the webinto proper position to be printed on the next printing-stroltc of theimpressioiH-ylin- (icis. Just as the cylinders.impinge the. web againstthe forms the looping-roller 6" commences its travel to the right,taking up the amount of web fed in by roll (it wliiletheimpressiorncyliriders are in impression, while the other spacing-rollerti" recedes to the right at the same speed,supplying the demands ol' thedelivery-roll if during the printing operation, thus preserving thetension of the paper and having all the time of the return ornon-printingstroke of the cylinders to readjustthe. web in readiness fora repeated operation, the spacing-rollers transi'erring the regularamount; of paper while the traveling cylinders are-oil impression andreturning out of contact over the typeforms. 'lhis enables a very easyacting cam 6* to be employed and insures a high speed witlisafet-y andwithout undue jerking of the web.

l igs. 3, -l, 5, and 6 are diagrams illustrating the method of printingthe web by means of two cylinders owrating on .one bed.

Fig. 2% shows the cylinders just ready to begin the printing-stroke, noimpressions having been made on the web, which is now stationary.
